Well I snagged an ATS standalone transmission controller and ATS select shift valve body (for my 48RE tranny) off of the TDR classifieds over a year ago 'cause the price was right. I am just now digging into all the details of my Excursion cummins swap (as I have accumulated parts over the last year or so). Here is a screen shot of the ATS monitor/datalogger software that runs on a laptop connected to the controller. It looks very cool and has all sorts of info available on it :cool: Anyone else have any experience using one of these?
